Application med Jimmy 1s, 1889.

Serial No. 296,538. (No model.)

`hereby declare the following to be a full,

clear, and exact description of the same.

My invention relates to the class of plugs for stopping up thedischarge-holes of sinks, tubs, basins' and other similar vessels orreceptacles; and my invention consists in the constructions andcombinations of devices which I shall hereinafter fully` describe andclaim.

Referring to the accompanying drawings for a more complete explanationof my invention,Figure l is a section of abasin, showing my plug in itslowest position acting as a stopper. Fig. 2 is aview showing the plugraised, serving as an escape and a strainer for the water.

A represents a sink, tub, basin, or other water-receptacle, having thedischarge-hole a. I B is the usual plate surrounding the discharge-hole,and havinga iiange, b, extending down into it. I

C is my plug, made of a hollow or tubular piece, the lower end beingopen, and the top, which is represented by c, being completely closed,and having the lifting-chain D connected with it. I

In the sides of the plug are made openings c', of various shapes, somecircular, some elongated, as slots or slits, as shown. The plug isseated in the discharge-hole, and can be lifted up and lowered downtherein. When fully down, the top c finds a seat in the plate B of thedischargehole and serves as a stopper therefor, resembling in thisposition an ordinary plug. 'lo let the water out of the vessel A, theplug C is raised, whereby its apertures come above the plate B and thewater passes through them and out the open bottom of the plug; but theforeign matter is stopped by reason of the aperture straining the water,and it collects on the outer surface of the plug. Now by lowering theplug all the foreign matter is scraped off its eXte-- rior surfaceagainst the inner rim of plate B, thus thoroughly cleaning the plug andleaving the foreign matter loose in the bottom of the vessel, whence itcan be readily removed.

It will thus be seen that no foreign matter can pass through the plug,which acts as a strainer, and thus prevents the trap from gettingclogged up, and every time the plug is pushed Vdown the foreign matteris scraped off and can be easily removed. Vhen the plug is down inplace, it does not interfere with the use of the vessel, because itstop, serving as the stopper, does not project up into the vessel anymore than doesl an ordinary plug. Now, in order to hold the plug in anelevated position, I form in its sides one or more slots, e, the lowerend, e', of which is curved to one side, as shown. In the inner rim orange, l), of plate B, I secure or form one or more pins or studs, E,which extend into the slot or slots e of the plug. Vhen the plug israised, its slots slip by the pins or studs until, reaching the curvedlower ends, e', the pins or studs enter them, the plug turning axially,and they then support said plug. To lower the plug, it is first slightlyturned to free the slot ends e of the pins or studs and then dropped.When the plug is raised by the chain D, the pins or studs entering thecurved lower ends of the slots cause the partial rotation of the plug ofthemselves, so that but a single lifting movement on the chain isnecessary to raise the plug to its extreme limit and place it inposition to be there held. The pins or studs E also serve aslimiting-stops to prevent the plug from being raised out of thedischargehole.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

l. The plug for the discharge-holes of sinks, tubs, basins, and othervessels, consisting of the sliding hollow or tubular piece having aclosed top, an open bottom, and apertures in its sides, in combinationwith the means for holding the plug in position to permit the escape ofthe water through its apertures, consisting of a fixed pin or stud inthe dischargehole, and a slot in the side of the plug, in which theiixed pin or stud fits, said slot having a curved lower end, with whichthe pin or stud engages, substantially as described.

2. The plug for the discharge-holes of sinks, tubs, basins, and othervessels, consisting of IOO the sliding hollow or tubular piece having aportion to hold the plug up, substantially as closed J(op, an openbottom, and apertures in described. f 1o its sides, and having also inits side an elon- In witness whereof I have hereunto set my gated slotterminating below in a portion hand.
